PLUG-TOBACCO FORM.

SPECIFICATION forming part of Letters Patent No. 489,900, dated January10, 1893. Application filed September 21 1892. Serial No. 44 4- N m l ToaZZ whom it may concern.-

Be it known that We, EDWIN A. HAN- oooK, ELIJAH E. LOVELACE, and THOMASF. LAWLEss, citizens of the United States, residing at Lynchburg, in thecounty of Campbell and State of Virginia, have invented a new and usefulPlug-Tobacco Form, of which the following is a specification.

This invention relates to tobacco mills; and it has for its object toprovide an improved plug tobacco frame or form adapted to be used inseries to make up the mill.

To this end, the invention primarily contemplates improvements in thebase or plun ger frame used in connection with the cell or die-frames,so that the improvement can be readily attached to and detached from theold style plunger base, while at the same time, providing a constructionin which the strain of the powerful pressure exerted upon the mill, isevenly distributed over the entire plunger base, which is entirelywithout weal: joints between the raised faces or cell bot-. toms.

With these and many other objects in view, which will readily appear asthe nature of the invention is better understood, the same consists inthe novel construction, combina tion and arrangement of partshereinafter more fully described, illustrated, and claimed.

In the accompanying drawingsz-Figure l is a plan view of a plug tobaccoform or frame, constructed in accordance with this invention, set up foruse. Fig. 2 is a vertical transverse sectional view on the line 3.3. ofFig. 1. Fig. 3 is a detail sectional view of the removable face plateillustrating a modified construction thereof. Fig. A is a detail edgeView and elevation of the spring actuated locking catch. Fig. 5 is atransverse sectional View showing several of the forms arranged one uponthe other.

Referring to the accompanying drawings:- A represents the flatrectangular metallic bed plate of the base or plunger frame, to theunder side of which is securely riveted by the rivets B, the die orplunger blocks C. The said die or plunger blocks C, are rectangular incross-section and are arranged in parallel rows, and at equal distancesapart, to leave intervening spaces D, which receive the partition wallsof the cell or die-frames hereinafter described, and the bottom faces ofsaid blocks C, are provided with metallic facing plates E, riveted inposition by the rivets B, and adapted to come in contact with thetobacco in the cells, in which the plunger blocks move. Thisconstruction is quite familiar to those skilled in the art, and tocomplete the ordinary base just described, side rails, F, are secured tothe top and on opposite edges of bed plate A, and are extended at theirends as at G, to form the usual handles, by means of which, the frame isreadily placed in proper position.

In the present invention, the opposite side rails F, are provided attheir lower inner edges with the opposite inner side grooves H, whichreceive the removable metallic sliding face plate I. The said metallicface plate, I, rests 7o flat upon the bed plate A, and has the edgesthereof engaging the opposite side grooves I-I, so that the same cannotonly be readily slid in and out of position, but also, so that anytendency of the said face plate to lift or rise with the cell ordie-frame is checked, and the said plate held firmly in position whilethe several parts of the mill are being separated after pressing. Theside rails F, are fn rther provided at their lower inner edges with theWear plates J, which plates form a portion of the top sides of theopposite grooves H, and therefore prevent the face plate, I, fromwearing the wooden side rails so that the same would fit loose in itsproper position. The removable face plate I, is provided in one edgethereof with a locking notch K, which after the face plate has reachedits proper position upon the bed plate A, is adapted to receive thelocking tongue L, at one end of the spring actuated catch lever M. Theother end of the catch lever M, terminates in a finger flange N, workingin the opening 0, in one of the side rails and providing means forreleasing the catch from the plate when it is desired to remove thelatter. The spring P, seated in one of the side rails,norrnally pressesthe catch into locking engagement with the face plate. The saidremovable face plate I, is further provided upon the upper face thereofwith a series of rectangular raised portions or cell bottoms, Q. Thesaid rectangular raised portions or cell bottoms Q, are prefer. ably cutout integrally with the face plate I,

by regularly indenting or grooving the same to leave intervening spacesR, which correspond in width and disposition to the intervening spacesD, between the die or plunger blocks 0, beneath the bed plate A, but itwill of course be understood, as illustrated in Fig. 3,that the saidraised portions or cell bottoms Q, may be separately riveted to the faceplate I, with the intervening spaces R,therebetween. Now, as the plungerblocks 0, snugly register with and fit into the top of the cells S, ofthe cell frames T, the rectangular raised portions or bottoms Q, whichare directly in line with and above the said blocks, snugly registerwith and tightly fit into the bottom of the cells of said frames to formclosed bottoms therefor, to prevent the tobacco from forcing its Way outof the bottom edges of the cells while undergoing pressure from theplunger blocks entering the top of the same.-

It will of course be understood, that the cell or die frames T, areconstructed in the usual manner so as to have a multiplicity ofpartitioned rectangular cells corresponding to the plunger blocks on thebase or plunger frame.

Although the face plate I, is removably placed in position upon the bedplate A, specifically as described, nevertheless, it will of course bereadily understood that the same can be otherwise removably fixed inposition by analogous means, without departing from the spirit of theinvention.

To those skilled in the art, the operation of employing the hereindescribed form, is well understood.

The first base or plunger frame is mounted upon a'suitable base, and thepartitioned cell frame mounted thereon between the side rails thereof,so that the bottom edges of the cells take into the spaces R, and thecell bottoms of the plunger frame snugly fit into the bottom of thecells. Each compartment or cell, receives its proper quantity oftobacco, designed to be pressed into plugs, after which the secondplunger or base frame, is mounted over the cell frame, so that theplunger blocks upon the under sides thereof fit into the top of thefilled cell frames. Several forms, the number varying according to thesize of the mill, are similarly placed in position, one upon the other,until the series is completed, which makes up the mill, and after whichthe pressure is applied to any desired degree, without fear of the plugsbeing formed, with spread edges from the spewing of the tobacco.

It is thought that the construction and operation and many advantages ofthe herein described frame or form are apparent without furtherdescription.

Having thus described our invention, what we desire to secure by LettersPatent is:-

1. In a plug-tobacco form, the combination with the bed plate and theseries of plunger blocks or dies secured to the under side of the saidplate; of a face plate removably seated on the said bed plate and havinga corresponding series of raised portions or cell bottoms, substantiallyas set forth.

The combination of the bed plate having a bottom series of plungerblocks or dies; of a face plate removably seated on said bed plate andhaving a corresponding series of raised portions or cell bottoms, meansfor locking said face plate in position, and the partition cell or dieframe, substantially as set forth. a

3. In a plug form for tobacco mills, the combination with the bed plate,and the transverse rows of plunger blocks or dies secured to the underside of said bed plate; of the opposite side rails secured to topopposite edges of said bed plate and having inner side grooves, aremovable face plate adapted to rest fiat upon said bed plate and slideWithin said grooves, said face plate being provided with a series ofraised portions or cell 9 bottoms corresponding to said plunger blocks,and a locking notch at one edge,a spring actuated catch adapted toengage said locking notch, and the cell frames registering with saidblocks and raised portions or bottoms respectively, substantially as setforth.
